エアロキャプチャー技術応用へ向けた希薄空力特性の初期検討

抄録

In this study, drag efficient was calculated based on the DSMC method, for the investigation of the flight path analysis of the aerocaputure mission. In DSMC method, rotational and vibrational energy exchange for CO molecules was considered. In the free molecular region, drag coefficient is calculated with canceling the collision routine of the DSMC method. As a result, in the free molecular region, the drag coefficient calculated by the DSMC method agreed with the theoretical one. Also, the relationship between the Knudsen number and the drag coefficient was observed.
